Photonic integrated circuits in silicon-on-insulator

We show a platform for silicon photonic circuits in silicon-on-insulator. In crystalline silicon waveguides have very low propagation losses and at the same time extremely good uniformity, which is essential for high-quality wavelength filters. Also, we can use deposited amorphous material to fabricate similar devices on top of any substrate (including CMOS) with only a small penalty in performance.
